Title: Logic circuit synthesizing device
Inventor: NAKAMURA YUICHI
IPC: H03K19/00
Filed: 1990-02-28
Abstract: PURPOSE:To reduce the scale of a logic circuit in a short calculation time with application of a logic formula by adding a redundant member to an input logic formula and extracting a factor out of the input logic formula via an algebraical method. CONSTITUTION:A member is added to a logic formula from a redundance adding device 5. In this case, a redundant member is used so that the member to be added is not affected by the output of the logic formula. Thus a new variable is not required. Thus such a factor that reduces the circuit scale is extracted out of the logic formula by a factor extracting device 4 owing to addition of the redundant member. If such a factor is not extracted even with addition of the redundant member, a redundant part deleting device 7 deletes the added redundant member. Thus it is just required to add the redundant member drawn out of the characteristic of the circuit with no addition of a new variable in a process where a logic formula is converted into a logic circuit. Then it is possible to obtain such a factor that reduces the circuit scale in a short calculation time.
